AUGUST SUNDI-I, OF HASTINGS UPON HUDSON, NEW YORK.

GATE-HINGE.

To all whom it may concern I Be it known that 1, AUGUST SUNDH, a

citizen of the United States, and resident of Hastings upon Hudson, in the county of WVestchester and State of New York, have invented a certain new and useful Gate- Hinge, of which the following is a specification.

This invention relates to hinges for gates and the like. An object of the invention is to provide a hinge which may be quickly and securely applied to an iron gate post, and which is simple, practical and durable, and at the same time inexpensive to manufacture.

Other features and advantages of the vention will appear hereinafter.

In the accompanying drawings, Figure 1 is a part sectional elevation of a gate hinge and connected parts, constructed in accordance with the principles of my invention. Fig. 2 is a fragmentary top plan view of the rotary hinge part,-the gate post also being shown in section. Fig. 3 is a view similar'to Fig. 1, but showing a different form of the invention.

Referring particularly to Figs. 1 and 2, the gate 1 may be hung on the gate post 5 by means of a hinge" comprising a stationary hinge part and a rotary hinge part, secured respectively to the post and gate. The rotary hinge member comprises sections 6 and 7 secured together in position around the post by means of bolts 8, and when thus connected form a cylindrical casing 9 open at the bottom and having at the top a restricted portion or neck 10 which'fits around the post 2 with only sufficient clearance between said neck and post to permit the rotary and up and down movements of the hinge member on the post.

The gate 4 is carried by said rotary member, being attached thereto as by means of a bracket or strap 11 formed to fit the rounded corner 12 of the gate frame, said bracket clamped to the hinge part 6 by means of bolts 13. The part 6 is also shaped to conform to the outline of the gate frame so that when the parts 6 and 11 are connected the hinge member is rigidly and securely attached to the gate.

The hinge as shown is of the gravity oper ated type wherein the gate is self closing when it has been swung in either direction to an open position. The stationary hinge member is in the form of asplit sleeve com- Specification of Letters Patent.

prising sections 14 and'15 to fit around the post and clamped thereon by bolts 16 extending through lugs 17 formed on said sections. formed with a spiral shaped bearing surface 18 concentric with the post. Said surfaces are upwardly and outwardly inclined from their lowermost point at which is normally supported a bearing roller 19 carried by an arm 20 forming part of the rotary hinge member. Said arm may be split vertically the two halves thereof forming integral parts of the sections 6 and 7 respectively.

Vhen the gate is swung in either direction 1 from its olosecl position the roller 19 rides up the corresponding inclined surface 18, the gate being thereby lifted as it rotates. When the gate is released it swings back by gravity to closed position. 1

The cylindrical casing 9, by inclosing the hinge mechanism including the bearing surfaces, protects said parts from exposure to the elements. and other external agencies. An oil groove may be provided to permit the bearings to be oiled at intervals. It will be noted that the construction herein shown permits the hinge parts to be quickly attached to the gate post and gate. The hinge is-adjustable vertically to any desired position on the gate post and may also be rotatably adjusted on the post to bring the gate into exact register with the opposite gate post. A very compact arrangement is also provided wherein the gate frame is held close to the post, the gate having its axis of rotation in said post. I

Fig. 3 shows a modified construction wherein the inclined bearing surfaces 18 are formed on the rotary hinge member. The

bearing roll 19 is mounted on an arm or support 20 projecting upwardly from the fixed sections 1 1 and 15, of the inner stationary hinge member. The arrangement here shown involves substantially a reversal of the cooperating bearing parts 18 and 19 of Fig. 1. The principal operation is the same as that pointed out in connection with Fig. 1. When the gate is swung open, the inclines 18 ride up on the roller 19 and when the gate is released it is returned by gravity.

Modifications of the constructions shown maybe resorted to without departing from the spirit and scope of my invention.

What I claim is,

1. A gate hinge comprising in combina tion, a stationary hinge member formed in Each of the sections 14 and 15 is sections to engage opposite sides of a post, means to clamp said sections to the post, and a rotary hinge member surrounding the post and having its axis of rotation concentric with the post, said hinge members having cooperating bearing surfaces.

2. A gate hinge comprising in combination, a stationary hinge member formed in sections to engage opposite sides of a post, means to clamp said sections to the post, and a rotary hinge member comprising a casing arranged to surround said post and stationary hinge member and inclose the stationary hinge member.

3. The combination with a gate post, of a split hinge member formed to surround the post, means to clamp said member to the post, and a rotary hinge member having a bearing part to run on said first mentioned member, the axis of rotation being Within said post.

l. The combination with a gate post, of a split hinge member formed to surround the post, means to clamp said member to the post, a rotary hinge part supported on said first mentioned member and made in sections to facilitate the mounting of the hinge on the gate post, and means to clamp said sections together so that they surround the p 5. The combination with a gate post, of a hinge part surrounding the post and adjustable vertically thereon, means to clamp said part to the post in its adjusted position, and a rotary hinge part mounted for rotation on said first mentioned part, said rotation being about said post as an aXis.

6. The combination With a gate post, of

a hinge part surrounding the post and adjustable vertically thereon, means to clamp said part to the post in'its adjusted position, and a rotary hinge part mounted for rotation on said first mentioned part and supported and guided by the gate post.

7. A gravity operated hinge comprising in combination, a split tubular member to surround a cylindrical post, means to clamp said member to the post, and an outer rotary hinge member comprising a casing surround ing said post and inclosing said first mentioned member, one of said members hav ing a spiral bearing surface, and the other member having a bearing part to run on said spiral surface.

8. A gravity operated hinge comprising in combination, a split tubular member to surround a cylindrical post, means to clamp said member to the post, andan outer rotary h'in 'e member com orisin a cas1n arran ed b 23 b b to surround said post and inclose said first mentioned member, one of said members having a spiral bearing surface, and the' other member having a bearing part to run on said spiral surface, said casing havinga restricted opening through which the post extends, whereby the rotary hinge member is supported and guided by the post as it rotates and moves up and down on the post.

Signed at New York city, in the county of New York and State of New York, this 14th day of February, A. D. 1916.
